Heterozygous is a genetic condition in which two different alleles are present at a particular gene locus. In other words, it is a condition in which a person has inherited different forms of a particular gene from each parent. By different forms, we generally mean that there are different portions of the gene where the sequence is different. Examples of heterozygosity: Tt, Rr, etc.

Phenotype is defined as the external appearance of an individual for any trait. It is observable and is determined by different combinations of alleles. For example, in the pea plant, the coloured flower represented by the genotype CC and Cc and the white flower represented by the genotype cc are the two phenotypes.
